Hi all,
I need to resample raster files on the command line.
First I thought that resampling would be an option of gdal_translate, but
it seems like it isn't implemented and there is a patch pending:
http://trac.osgeo.org/gdal/ticket/1724 - but this patch is against an old
version.

Hi list,
I'm extending the ImageIO-Ext's supported formats. Now I'm adding ENVI Hdr
format support.
1) Where could I find some sample data available in that format?
I have already taken a look at http://download.osgeo.org/gdal/data/...

Hi,
I managed to solve my problem with the GCPs in MEM driver (and sorry if I
bothered some with
that thread), which turned up to be due to a bad initialization of the dataset
geotransform.
After that I wrote a MEX version of gdaltransform to be able to reproject
points using GCPs.
This MEX

So one question is, why warping with GCPs takes such large amount of

Is the memory fragmentation really related to the use of many GCPs? Does

Frank,
Maybe I was not clear enough, but the memory segmentation has nothing to do
with the GCP warping. It results from loading the gdal.dll
For example, on a fresh start if I call (one other MEX for reading)
gdalread
without arguments, it prints the usage on screen.
Joaquim,
OK. Well, generally speaking GDAL should allocate relatively little
memory just on loading the DLL (and perhaps calling GDALAllRegister()).
So I don't know why you are seeing the problem you see.
Frank,
It's ok. I was not expecting an easy answer but I think this issue worth
Hi,
I'm fairly new with GDAL, and have been working with a coworker who is a
little more familiar with GDAL and gdalwarp, but we are both stumped by
this particular issue.
I have a GeoTiff image that is in a north polar Lamber Azimuthal Equal
Area (laea) projection. I am trying to
Hi again list,
I'm back to work on setting ECW format as a GDAL external plugin on windows
XP with visual studio 7.1 (nmake command line).
I have some issues...
My main steps are:
- building GDAL without ECW
- building ECW driver on frmts/ecw separately.
- configuring an ENV variable

Thanks for the help. I tried doing this, and ended up with the same
image (even diff found them to be the same). Here are the various
commands I tried. Maybe I'm just using the -wo option wrong.

The image I've been trying to convert is at this URL. It's about 6MB,
hopefully that's not too big.

Basically, I'm trying to convert it to a plain-old EPGS:4326 (latlong

I appreciate you taking a look.
Hi All,
Just had an email from a client complaining about the nan values that I
included in some Arc/Info ASCII Grid files that I sent them. The files were
created by converting GeoTIFF's into ASCII Grid format via gdal_translate.
I personally like that the nan's were carried through, but I
ROTFL You could also potentially do it with by ascii search and replace in
the resulting grid file
You are SO right! I had totally forgotten that this was ASCII output. Doh!
Thanks Frank.

Does this aspect really have anything to do with the number of GCPs?
Are you using the GDAL warp algorithm?
Oh yes, with 2500 GCPs I can do the warping. And yes I'm using the

Sorry for being so dumb. The GCP warping
